【摘要】 本文对三山岛金矿的采场回采开挖效应进行了数值模拟,结果表明,断层夹泥时断层带及围岩中的应力分布状态与不夹泥时具显著的区别,对采场及围岩的稳定性带来显著的不利影响。更多还原

【Abstract】 In this paper,the numerical simulation on the excavation effect of the stope of Sanshandao Gold Mine,the results show that the distribution condition of stresses in the fault zone and the surrounding rock have the obvious difference for the faults with the fault clay and no fault clay,this have the obvious unfavourable effects to the stability of the stope and surrounding rock.更多还原
